Thomas Herbert, 8th Earl of Pembroke and 5th Earl of Montgomery, KG, PC, PRS (c. 1656 – 22 January 1733), styled The Honourable Thomas Herbert until 1683, was an English and later British statesman during the reigns of William III and Anne.
Herbert was the third son of Philip Herbert, 5th Earl of Pembroke and his wife Catharine Villiers, daughter of Sir William Villiers, 1st Baronet. He was educated at Tonbridge School, Kent. Both of his brothers (the 6th Earl and the 7th Earl) having died without a male heir, he succeeded to the earldoms in 1683.
Herbert was returned unopposed as Member of Parliament for Wilton at the two general elections of 1679 and the general election of 1681. He was no longer able to sit in the House of Commons after assuming the peerage in 1683. From 1690 to 1692 as Lord Pembroke, he was First Lord of the Admiralty. He then served as Lord Privy Seal until 1699, being in 1697 the first plenipotentiary of Great Britain at the congress of Ryswick. On two occasions he was Lord High Admiral for a short period; he was also Lord President of the Council and Lord Lieutenant of Ireland, while he acted as one of the Lords Justices seven times; and he was President of the Royal Society in 1689–1690. He is the dedicatee of John Locke's An Essay Concerning Human Understanding and Thomas Greenhill's The Art of Embalming.
